The AEM cold air intake for 2017–2018 Subaru Impreza 2.0L replaces the restrictive factory airbox and is designed, tuned and dyno-tested to deliver more horsepower and torque. It uses an oil-free Dryflow synthetic filter rated for up to 100,000 miles before cleaning in ideal conditions, a custom heat shield to reduce intake heat, and a mandrel-bent aluminum tube with a gunmetal-gray powder coat. Backed by AEM's lifetime limited warranty; check applications for California legality.
